Notification and public disclosure of transactions by persons discharging managerial responsibilities and persons closely associated with them

As announced on 27 July 2023, Richard Tyson joined Oxford Instruments plc on 1 October 2023 as Chief Executive. On 14 November 2023 Richard was granted three awards of nominally priced options over ordinary shares of £0.05, under the Oxford Instruments plc Long Term Incentive Plan (the "LTIP"), as set out below.  These awards comprise the buy-out arrangements which replace Richard’s 2021, 2022 and 2023 LTIP awards from his previous employer, TT Electronics plc, which lapsed in connection with his joining the Company.

Award	Number of shares	Vesting date	Exercisable until
Buy-out of LTIP granted on 16 March 2021 by TT Electronics plc	27,872	16 March 2024	15 March 2031
Buy-out of LTIP granted on 14 March 2022 by TT Electronics plc	30,975	14 March 2025	13 March 2032
Oxford Instruments plc FY24 LTIP award	53,023	31 July 2026	13 November 2033

The awards will ordinarily vest and become exercisable as set out above, subject to the grantee’s continued service and to the extent to which the performance conditions are met. The buy-out awards will vest based on the achievement of the original TT Electronics plc performance targets. The Oxford Instruments plc FY24 LTIP award will vest based on the achievement of the performance conditions which can be found in the Directors’ Remuneration Report in the Company’s 2023 Annual Report. A two-year post-vesting holding period applies to all awards. Dividend equivalents will also be awarded and will accrue for the period from grant to vest and for the holding period (two years after the awards vest). No consideration was paid upon the grants of the awards and consideration of £0.05 per share is due upon the exercise of the awards. The awards were based on an Oxford Instruments plc share price of £21.50.

Full details of the awards, including performance conditions, will be provided in the Directors’ Remuneration Report within the Company’s 2024 Annual Report.
